Integrated mini vacuum pump with ASC (Air Saving Control) LEMAX series

Integrated mini vacuum pump with “ASC” (Air Saving Control), LEMAX series

The COVAL innovation intelligent vacuum pump series originates from Twintech technology. Twintech is an ‘all in one’ concept which for the first time integrates all the necessary components at the heart of the vacuum pump. Thus the user eliminates the need to order and assemble the individual components such as electro valves, pilots, vacuum switches, pressure regulators, filters etc. The modular aspect of the intelligent vacuum pumps also allows the user to choose only the functions needed for the application.

Integrated mini vacuum pump with “ASC” (Air Saving Control), LEMAX series


LEMAX is a new mini vacuum pump integrating technologies developed by COVAL for better productivity, efficiency and energy savings. It has a wide range of applications: packaging, robotics, plastics.

For the first time LEMAX integrates technology known as ASC (Air Saving Control). It generates energy savings of between 60% and 97%, depending on the products to be handled. The ASC activates to limit energy consumption at two levels:

  • Integrated vacuum regulation: reduction of energy consumption and noise level.
  • The ASC analyses the application and adapts itself to the airtight or porous pieces in order to optimize operation and energy consumption.

The advantages of LEMAX:

  • Unequalled compactness: fixed very close to the suction cups for short response times.
  • Smart communication: Easier experience at all stages: initial settings, production, maintenance.
  • Modularity

Branch-specific applications



Supply: Non-lubricated filtered air, 2 to 6 bar
Temperature: 0 to 60°C / 32 to 140°F
Contact output: PNP all-or-nothing NO or NC, adjustable hysteresis
Anti-parasite function: Integrated with LED display LED
Blow-off rate: Adjusted by flow restrictor
